Simple question regarding ai bits in Pokemon Ultra Sun/Moon

[Apollo ChaoZ]

Just a simple question here: What order of Ai bits make it harder?

You can make lots of combinations of them, like you can have 'strong' and 'basic' checked, or all three of them checked and I'm just wondering if it just uses whatever the highest level checked is. And if that's the case why are they in random combinations in the editor?
